After crashing: 'Leave, ET -- get uplift!' (7)
I believe the answer is:
elevate
'uplift' is the definition.
(to elevate is to lift up)
'after crashing leave et' is the wordplay.
'after crashing' is an anagram indicator (the original order crashes or breaks).
'leave'+'et'='leaveet'
'leaveet' with letters rearranged gives 'ELEVATE'.
'get' is the link.
(Other definitions for elevate that I've seen before include "Raise or lift" , "Hoist" , "Lift - exalt - promote - cheer" , "Raise to a higher position" , "Improve morally" .)
